Depends on your setup. I’m a btrfs guy, so I’d go with something similar as your other reply. It’s just as easy to remove/replace/add drives. They don’t even have to match in size. Just remember to balance after doing modifications to your array.

Whatever you get, get at least two and do RAID1/5/6. They will break.

Speed shouldn’t be an issue for streaming media.

Inspired by xkcd’s thing explainer I generated a list of how often words appeared in subtitles on opensubtitles for my target language.

I whipped those into a database, added manual translation for the top-1000 and started quizzing myself with a tiny php script.

It was more fun to code than to actually quiz myself. I think I played the top-100 before I got bored.

The Android client seems to have dropped a few player engines in a recent update. Previously there was an option to use libvlc, omxplayer or a third option that I can’t recall. Seems the developer opted to go with the worst option.

The AndroidTV app can use external players such ss VLC. I went with kodi as a client instead.
